Title: Improvements in or relating to lead-through insulators
IPC: H01B17/28
Filed: 1928-04-05
Abstract: 307,647. Pollak, J. E., (Hermsdorf- Schomburg-Isolatoren Ges.). April 5, 1928. Insulators.-The body of a lead-in insulator is formed with an annular channel along the part which is surrounded by the supporting-flange, and the inner surface of the channel has a conducting coating which is connected electrically with the supporting flange. The space between the flange and the insulator body reduces the formation of the corona at the junction of the flange and the body, and it also reduces the risk of breakdown by puncture. The same construction may be applied to the junction between the insulator and the lead-in conductor. In the construction shown in Fig. 1, the insulator body J is connected by a supporting-flange F with the cover of a transformer, for example, and a gap A is left between the insulator and the flange. The surface of the part of the insulator around the gap is provided with a conducting covering L by metal spraying or other suitable means, and metal wedges are inserted in the gap A to secure the insulator in place and to connect the flanges electrically with the metallic layer L. A hollow space or channel H may be provided above and below the flange, and the coating L may be extended into this channel. The petticoat W which forms the channel H may be suitably shaped to facilitate the insertion of the insulator in the flange in order to avoid making the flange in two parts.

Title: Improvements in detonators
IPC: F42B3/195
Filed: 1932-04-13
Abstract: 387,545. Blasting-detonators. BIAZZI, M. F. F., Brigue, Switzerland. April 13, 1932, No. 10634. Convention date, April 29, 1931. [Class 9 (i).] In manufacturing a blasting- detonator comprising a secondary charge 3 in a case 1 surmounted by a primary charge 4 in a capsule 2, the primary charge is compressed in its capsule before this is inserted in the case 1 over the secondary charge which has been previously compressed therein, and the capsule is then pressed down to insure intimate contact between the two charges. By this process, the primary charge has its zone of highest compression against the zone of highest compression of the secondary charge, a disposition most efficient for the transmission of the detonation. This separate compression of the primary charge also enables this charge to be more highly compressed than the usual process of compressing the primary charge direct into the case 1. The detonator may contain a primary charge of mercury fulminate in a copper capsule in an aluminium case containing a nitroaromatic compound ; or the case may be of copper and the capsule of aluminium filled with lead azide. Part of the secondary charge may be inserted in the capsule ; or an intermediate charge of nitropentaerythrite, trimethylenetrinitramine or the like may be used. The hole 6 in the base of the capsule may contain some of the primary charge or a small charge of flash transmitting composition to facilitate ignition. Specification 239,773, [Class 9 (i), Ammunition &c.], is referred to.

Patent GB-109463-A (GB)
IPC: F16H15/46
Abstract: 109,463. Rhodesian Enterprises Ltd., and Molesworth, H. B. Aug. 17, 1916. Reversing-gearing.-Frictional reversing-gearing is so arranged that the pressure of contact between the friction surfaces varies automatically with the energy transmitted in both directions of motion. Two driving friction wheels 13, Fig. 1, rotated in opposite directions by chains 15, are mounted on radial arms 8 connected by a bar 12 in such a way that either wheel can be swung into contact with the internal surface of a driven wheel 3 on a shaft 2, the drive between the wheels in engagement tending to increase the frictional contact. In a modification, applicable for driving two propeller shafts of a boat,' another shaft 2 and wheel 3 are placed on the opposite side of the driving-shaft 1, and are driven independently by similar friction wheels, which however are caused to rotate in opposite directions to the wheels 13 by intermediate gear-wheels. Fig. 6 shows an arrangement for reciprocating the table of a planing, filing, or like machine. The friction wheel 13 engages either of two bars 4<1>, 4" connected to the table, and is moved automatically from one to the other at the end of each traverse by inclined stop 29. In a modification, two friction wheels rotating in opposite directions are mounted on diverging radial arms 8 and engage a single bar 4<1>. Either wheel is thrown into engagement with the bar, automatically or otherwise, by a lever. This gearing may be designed to give a quick return movement of the table. An arrangement similar to that shown in Fig. 1 may be used to rotate the threaded operating-shaft of a planing-machine, the chain-wheels 10 being of different sizes to give a quick return movement. Fig. 13 shows a modification in which, a friction wheel 13, or two wheels 13, 14 of different sizes on the same axis, are swung around a driving-shaft 1 to engage either internal or external friction surfaces 4, 4' on a driven member 3. In this arrangement, the shaft 1 may be driven by the member 3.
